Abstract

This paper describes the development of a distributed sensing system that can be disseminated in an environment of interest to monitor the vibration of a structure. This low-cost system consists of several sensor nodes and a central receiving node. All nodes are built using off-the-shelf electronic components. Each of the sensor nodes is battery-powered and equipped with a triaxial MEMS accelerometer, a wireless Long Range (LoRa) transceiver module for data transmission, a GPS module used for synchronization, and a microcontroller. The operation of the sensor node is validated by controlled laboratory tests where it is compared to a commercial reference accelerometer. Furthermore, the feasibility and potential benefits of the application of the proposed system to a structure in an archaeological site is investigated. Results show that the proposed sensor node could successfully monitor the vibration at several locations within the site. Therefore, it may be employed to detect the most relevant stresses to the structure, allowing for the identification of risks.

摘要

本文描述了一种分布式传感系统的开发，该系统可以在感兴趣的环境中传播，以监测结构的振动。该低成本系统由几个传感器节点和一个中央接收节点组成。所有节点均使用现成的电子元件构建。每个传感器节点都是电池供电的，并配备了三轴 MEMS 加速度计、用于数据传输的无线远程 (LoRa) 收发器模块、用于同步的 GPS 模块以及微控制器。通过受控的实验室测试验证了传感器节点的运行情况，在该测试中，它与商业参考加速度计进行了比较。此外，还研究了将所提出的系统应用于考古遗址中的结构的可行性和潜在好处。结果表明，所提出的传感器节点可以成功地监测遗址内多个位置的振动。因此，它可用于检测对结构最相关的应力，从而识别风险。
